Zune software is bad

This Zune software is terrible. I can't buy one song from the Zune marketplace. I'm asked to sign in 500 times, even though I tell Microsoft to remember me. And then when I think I'll get to the page I want (buy this song, or account management), I'm taken to the support page. The support page is not what I wanted. I wanted to buy one song (yes, I clicked on the song). Since the support page was there, I went on to see how to buy a song. I can't read it! The background is black and the font is... black too! Wonderful, beautiful. But I can't do anything with this software. I have to create software and it has to be good. Why can't Microsoft do better?
